There is no way we could all ever agree on a universal definition of what constitutes a stupid idea. Jumping off a building is a good idea if it’s on fire and there’s a giant pillow down below. Rather than calling any ideas stupid, in case we offend any flat-earth snowflakes out there, we should instead refer to certain concepts as unpopular.In 2014, a paper published in Public Opinion Quarterly found that people’s beliefs can be challenged by wording questions differently. When a crazy idea is left to fester on the fringes it poses no threat to society.
